Ambry Genetics

Feb 23, 2023

The c.427C>T (p.R143W) alteration is located in exon 4 (coding exon 4) of the ADGRA2 gene. This alteration results from a C to T substitution at nucleotide position 427, causing the arginine (R) at amino acid position 143 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
